Newest batch of 3570K's OCing like crazy - Page 50

2nd - 3238B908 - idles hot 41c, @4.4 86c, can't seem to get past 44
3rd - 3243B598 - Yet to test

UPDATE: Finally got to play with #3 and there may be some truth to the 324 batch, at least for me. #3 seems to take less voltage, but it still runs hot like #2. However, when running IBT, there is usually a huge temp spread between standard and very high settings, about 10C sometimes. With #3, there is only about a 2C spread between those settings.

And most importantly, batch 324 actually got me to 5.0 Ghz @ 1.485v. I know that it can go higher, but it will need far superior cooling and delidding, because the temps are insane at a throttling 105c.

5.0 does really require some voltage doesn't it? I didn't like the temps I had either, though it never throttled, I used Prime and not IBT.

My #2 proc can go higher too, but it will take way too much voltage. The video below is really great, straight from an Intel guy that is an OC enthusiast. My takeaway from his comments are:

  • Heat doesn't kill processors, voltage does
  • Max voltage should never be beyond 10% of max when overclocking.
  • Taking the above example that means you should never go past 1.54v unless you're on cryogenics

What I mean is look at the die size, its the same as Ivy but packed with more transistors which heat up, now it has a higher watt rating meaning it will yield much more heat over the same die size, to achieve really fabulous overclocks you need atleast the swiftech h220, ivy has proven to be elusive when it comes to heat management by coolers, now imagine Haswell under H220 if Ivy is already reaching H220's higher limits, are you really going to see Ivy high clocks with it? I doubt. If Haswell was comming in at 18w less like the difference between Ivy and Sandy, there may be a chance of really good overclocks occurring frequently accross chips, now I actually doubt it unless like you will once in a while see, a "rogue" haswell pulling gymnastic stunts in OC (mad crazy Haswell hitting 5.5Ghz on water at acceptable parameters for longterm use)

As far as Ivy is concerned I saw somewhere that A (5th letter in the batch) means the chip will require less vcore but yield tones of heat, the B will require more vcore and yield less heat (my i5 experience exactly) the C and D are undocumented. Am really curious to know what C and D really signify.
Hmm you're right, anyway thx for the info thumb.gif

A bit of both, some batches have had a good number of great clocking chips so chances of a great chip can be better, but then those same batches also have some terrible chips.
Some batches may be better than others, but still playing the lottery when looking for a good one.
Hi FtW 420, just wanna ask is it also fake information about this : List of Intel CPU Batch ??

My chip is also can do 5GHz but with abit higher volt which is 1.495 biggrin.gif but only test it with superpi 32M and AIDA memory benchmark :

What do you guys think? I just got done doing 48 hours of folding non-stop at 4.5Ghz @1.16Vcore, this screenshot is almost an hour into another fold-a-thon. I've tried 4.7 @ 1.19 and it ran, but I haven't flogged it against FaH, but I'm about to once this work-unit is done. I'll let you guys know my results.

Ok here's the update: Pushed it to 4.7Ghz, but the voltage increase was 0.09 volts from 4.5Ghz @ 1.16Vcore. Currently running 4.7 Ghz @ 1.25Vcore.

CPU Batch#: 3222C554

Very nice man, I need 1.325V for 4.5.
